| Abstract | Transition-metal sulfides are key cathode materials for thermal batteries used in military applications. However, it is still a big challenge to prepare sulfides with good electronic conductivity and thermal stability. Herein, we rapidly synthesized a Co-doped NiS2 micro/nanostructure using a hydrothermal method. We found that the specific capacity of the Ni1-xCoxS2 micro/nanostructure increases with the amount of Co doping. Under a current density of 100 mA cm(-2), the specific capacity of Ni0.5Co0.5S2 was about 1565.2 As g(-1) (434.8 mAh g(-1)) with a cutoff voltage of 1.5 V. Owing to the small polarization impedance (5 m Omega), the pulse voltage reaches about 1.74 V under a pulse current of 2.5 A cm(-2), 30 ms. Additionally, the discharge mechanism was proposed by analyzing the discharge product according to the anionic redox chemistry. Furthermore, a 3.9 kg full thermal battery is assembled based on the synthesized Ni0.5Co0.5S2 cathode materials. Notably, the full thermal battery discharges at a current density of 100 mA cm(-2), with an operating time of about 4000 s, enabling a high specific energy density of around 142.5 Wh kg(-1). In summary, this work presents an effective cathode material for thermal battery with high specific energy and long operating life. |
